I am posting this for a friend that has a Weatherby Accumark in 7MM Mag - not sure of the barrel length (24"?) or twist (1:9.5"?) but he is now using a HSM 180gr Berger VLD grouping ~1.00" at 100 yards. Prior to that he was using 160gr NABs (IIRC), same or close to the Berger grouping.

I offered to load for him if he buys the dies (I have a 7MM STW dies but not the 7MM Mag dies) and whatever bullet he wants but he insist staying with factory ammo. Anyways, not sure where he read it but apparently he is convinced that a 168gr will group better. HSM has 168grainers.

Shots will be all under 500 yards, most likely 200-250 yards. Looking forward for any information to pass to him. Thank you in advance for your support and understanding.

Ed, If it were me I would start with the cheapest ammo shooting bullets in the 175 class and heavier. BC is not a factor and any accuracy of MOA or less is plenty good to 500 yds. I have read (and experienced) plenty of reports of cheap ammo shooting just as well or better as the premium stuff.

Wbm, he's sighted in at 2.5" at 100 yards with the 180 Berger with an MV of 2850 FPS (chronoed).

Mark, IIRC he used to shoot corelokts with basically the same result ... and the same reason I offered to load for him. I told him the same thing about standard vs preimum ammo but he's a bit on the stubborn side.

Your friend should try Federal's products which in my opinion are of top quality. For large game like elk he needs ammo that penetrates and delivers good terminal performance. 160gr. Nosler Partition, 160gr. Trophy Bonded Tip (my favorite) and 175gr Trophy Bonded Bear Claw.
